Transmission electron microscopy of J774 macrophages infected with L. pifanoi. A and B. TC1 and TC2 treatments caused loss of phagolysosome bulkiness, abundant electrodense vacuoles. C Control without treatment. D. SS treatments with empty vacuoles, E. TC1:SS (1:1), F. TC2:SS (1:1). The images are representative of the findings for each treatment group. f: Phagolysosome N: Macrophage nucleus n: L. pifanoi nucleus k: Kinetoplast pf: Flagellar pocket Vd: Parasitic degradation vacuums. The white arrows indicate the thinning of the phagolysosome (A) and the empty vacuoles (D, E and F).
